Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An insecure component vulnerability exists in Magento 2.2 prior to 2.2.10, Magento 2.3 prior to 2.3.3 or 2.3.2-p1. Magento 2 codebase leveraged outdated versions of HTTP specification abstraction implemented in symphony component.

Recommended fix High confidence

Magento 2.2.10+ or 2.3.3+ (latest respective 2.2.x or 2.3.x release)

  1. 1. Verify current Magento installation version using bin/magento --version or admin panel
  2. 2. For Magento 2.2.x versions: Schedule upgrade to version 2.2.10 or later (preferably latest 2.2.x)
  3. 3. For Magento 2.3.x versions: Schedule upgrade to version 2.3.3 or later (preferably latest 2.3.x)
  4. 4. Create full backup of codebase, database, and media files before upgrading
  5. 5. Enable maintenance mode: bin/magento maintenance:enable
  6. 6. Run composer update to pull new version: composer require magento/product-community-edition=X.X.X --no-update (replace X.X.X with target version)
  7. 7. Update composer: composer update
  8. 8. Clear caches and regenerate DI: bin/magento cache:flush && bin/magento setup:upgrade
Caveat Patch releases (e.g., 2.2.9 to 2.2.10) typically contain only security fixes with no breaking changes; verify compatibility with custom code/themes
